1. 1 Image Retrieval in the Wild CVPR 2020 Tutorial on Yusuke Matsui The University of Tokyo Takuma Yamaguchi Mercari Inc. Zheng Wang National Institute of Informatics
2. 2 Yusuke Matsui ✓ Image retrieval ✓ Large-scale indexing http://yusukematsui.me “Reconfigurable Inverted Indexing”, ACMMM 18 “A Survey of Product Quantization”, ITE 18 Lecturer (Assistant Professor), the University of Tokyo, Japan @utokyo_bunny
3. 3 Takuma Yamaguchi Engineering Manager, Mercari, Inc. https://www.linkedin.com/in/kumon-takuma-yamaguchi/ • OCR • Image Restoration • Super Resolution • Distributed File/Computing System • Image Recognition System • Visual Search System
4. 4 Zheng Wang ✓ Person Re-identification ✓ Instance Search https://wangzwhu.github.io/home/ “Learning to Reduce Dual-level Discrepancy for Infrared-Visible Person Re-identification”, CVPR 19 “Beyond Intra-modality: A Survey of Heterogeneous Person Re-identification”, IJCAI 20 JSPS Fellowship Researcher, National Institute of Informatics, Japan
5. 5 Image retrieval ➢ Significant progress has been made in the last decade ➢ However, evaluation is based on existing datasets ➢ No enough discussion about how to create a practical and large- scale visual search system Paris dataset: https://www.robots.ox.ac.uk/~vgg/data/parisbuildings/
6. 6 Practical and large-scale visual search system for real-world applications ✓ Discovering visually similar items in online marketplace apps ✓ Re-identification for pedestrians in a security scenario.
